How hard does atmospheric drag push on the ISS? Is it more than one pound?
A comment under this question has me thinking; with it's huge main structure and giant solar panels the ISS presents a very large cross-section to Earth's rarified atmosphere at 400 km altitude. So ...

Would ISS raise up with the help of the self-powered ion thrusters?
The solar arrays provide about 100 kW of power, so we can put the two HiPEP thusters providing 1 N (1000 mN) power combined, with the specific impulse as high as 6000–9000. Such an acceleration force ...
